mixed plastics MRFs

Mixed plastics MRFs process mixed plastic bottles collected from either kerbside schemes or bring sites. O.Kay offers everything from single sorting lines to fully automated recycling systems.

Whether you are looking to build a zero-labour plant or a low-capital single picking line, O.Kay will devise a plastics recovery system to suit your required footprint, budget and operating costs. We will also provide guaranteed recovery, purity and availability rating on all our equipment.

The advantages of O.Kay mixed plastics MRFs

• Optical autosort units and mechanical screens to recover plastics automatically
• Autosort units sort plastics into all polymer types
• Autosort units sort plastics by colour
• One, two or three-way autosort units available for multiple material recovery e.g. PET clear, PE coloured and HDPE natural
• Autosort units can remove contaminants from all plastics streams to ensure best market prices
• Touch screen panels on autosort units allow operators to change the materials to be recovered within seconds. This negates problems associated with any variations in incoming materials.
• Air separation systems can remove the lights fraction for improved market prices
• The quick and easy separation performed by the autosort units and the mechanical screens allows very high throughputs over the system
• The plastics recovered at our MRFs meet UK mill specifications
• We include points of access for the direct baling of monofraction materials from bring sites.
• We design the MRF to use automated or manual sorting to match capital budget
• Presort stations to remove large non-recyclable items
• All our MRFs are fully guarded and covered to protect operators around the MRF

Best quality recovered product

O.Kay is an expert supplier of design-and-build systems capable of processing all tonnages of plastic bottles. Depending on the throughput, we use a mix of mechanical screens, autosorts, magents, eddy currents and picking/inspection stations to recover top quality materials for sale to UK mills and reprocessors.

Materials Recovered

PET Natural, coloured or mixed
PE Clear, coloured or mixed
HDPE natural, coloured or mixed
LDPE/Plastic Film
PVC

What the optical autosorts units can do

The optical autosorts can positively sort:

• Plastic containers by polymer and / or
• Plastic containers by colour

The optical autosorts can negatively sort:

• Contaminants from plastics

Worker safety

Whether we are installing a single sorting line or a high-tonnage automated MRF, we take the safety of our workers – and the safety your staff – very seriously. Our engineers are trained to the latest UK H&S standards and they infuse these standards into all our designs. They also arrange the in-depth training of all your operating staff so they too will work safely to the highest standards.

Typical equipment within a Mixed Plastics MRF

Air Knives – to suck/blow out the lights fraction from any stream
Bag Openers – to open bags/sacks and release recyclables
Balers – to reduce the recovered product in size for reduced transport costs
Ballistic Separators – to separate flat-and-light items from rolling-and-heavy items
Bottle Perforators (Plastics) – to pierce and flatten plastic bottles for increased storage and reduced transport costs
Bottle Perforators (Glass) – to smash glass bottles for improved downstream sorting
Cabins – to protect sorters (shelter, heating, ventilation and air conditioning)
Can Crushers – to reduce the size/volume of recovered cans in storage bunker/transport
Conveyors – to transfer material to the screens, separators and bunkers
De-stoners – to separate heavy materials from light materials Disc (Card) Screens – to remove the fines fraction, to sort papers and card
Eddy Current Separators – to remove the non-ferrous content
Electro and Overband Magnets – to remove the ferrous content
Metering Systems – to allow front-end storage and a ‘perfect-flow’ feed into MRF
Paper Autosorts – to automatically separate all packaging, grey board and brown board from the News fraction using NIR (near infrared) detectors and CYNK (cyan, yellow, magenta and black) detectors and cameras
Plastic Autosorts – to automatically remove all plastics by polymer type and/or by colour
Pre-sorts – a type of picking belt used ahead of the primary screen to remove large contaminants
Picking Belts – to allow human sorters to sort materials or inspect recovered materials
SCADA Control Systems - to monitor and control large plants remotely
Trommels – to separate all types of materials by size (two, three or four-way splits available within single drum)
Walking Floors – to allow fast dumping of materials from trucks onto walking floor, which feeds materials into system. Also used in bunkers to walk materials onto baler feed conveyor
